@glparker4, the simsub situation you're describing doesn't make sense, since the simsub is done at the Telus head-end. In fact, if you have 2 boxes tuned to the same channel number, the signal is multicast to both boxes by the modem/router. If you double-check that they are on the same channel number and find you are getting different simsubs, please post your modem/router details and a full description of the connections.
You can check the the number of HD and SD streams on your PVR by pressing:
Menu, Settings, General, System Information, System Resources.
